MD485 Configuration
a. Base MD485
1) Active Ports – “RS-232 and RS-485”
2) Communication Mode – “Transparent Communication”
3) RS-232 Port Configuration – Desired baud rate
4) RS-485 Port Configuration – Desired baud rate
b. Remote MD485
1) Active Ports – “CS I/O and RS-485”
2) Communication Mode – “Transparent Communication”
3) CS I/O Port Configuration – Modem Enable
4) RS-485 Port Configuration – Desired baud rate
RF401 Configuration
The active interface of the base RF401 should be set to “COM2xx to
RF401”. All other RF401 settings maybe left in their default state.
However, if there is a neighboring RF401 network, you should change the
Hopping Sequence of base and remote RF401s to a new setting to avoid
interference.
